Selling, general, and administrative (SG&A) expenses also decreased by 67% to $17.1 million, reflecting cost discipline following the commercial product discontinuation.
The company’s cash position stood at $176.5 million at year-end, supplemented by a $65.5 million net proceeds from a January 2025 public offering. This capital infusion extends Amylyx’s cash runway through the end of 2026, supporting the execution of multiple clinical programs and commercial preparations for avexitide.
- Expense Reduction Enables Focused Investment: Lower R&D and SG&A expenses reflect a strategic pivot from commercial activities back to clinical development.
- Cash Flow Impact from Product Discontinuation: Payments totaling $31 million in Q4 related to product returns and purchase commitments weigh on cash usage but are expected to conclude in 2025.
- Capital Raise Secures Operational Horizon: The recent equity offering provides financial flexibility to advance pivotal studies and prepare for potential market entry.
Overall, Amylyx’s financial profile demonstrates a transition phase prioritizing clinical validation and operational streamlining ahead of anticipated regulatory milestones.
Executive Commentary
"We are excited to have started the pivotal study of Avexatide for the treatment of post-bariatric hypoglycemia and anticipate top-line results in the first half of next year. We also recently completed a financing, raising approximately $65.5 million to begin commercial preparations for Avexatide and to extend our cash runway through the end of 2026."
Justin Klee, Co-Chief Executive Officer
"With these resources, we expect our cash runway to take us through 2026. These milestones are data from the phase III lucidity trial of Avexatide and PBH, data at week 48 from the ongoing Helios trial in Wolfram syndrome, the unblinded interim analysis of the phase IIb portion of our Orion trial in PSP, and data from our phase I Lumina trial of AMX114 and ALS, along with commercial preparations for the potential first-to-market launch of Avexatide and PBH."

Strategic Positioning
1. Pivotal Phase 3 Trial Launch for Avexitide in PBH
The initiation of the LUCIDITY trial, a randomized, double-blind, placebo-controlled study enrolling approximately 75 participants with PBH following Roux-en-Y gastric bypass, represents a critical inflection point. The trial’s design mirrors successful Phase 2 studies that demonstrated statistically significant reductions in hypoglycemic events, positioning avexitide as a potential first-in-class therapy for a condition with no approved treatments. Recruitment is progressing with dosing expected to begin in March or April 2025, and topline data anticipated in the first half of 2026.
2. Strengthened Commercial Leadership and Preparations
The appointment of Dan Monahan as Chief Commercial Officer underscores Amylyx’s commitment to building commercial capabilities ahead of a potential 2027 launch. Monahan’s experience in launching industry-leading medicines equips the company to address the estimated 160,000 U.S. patients living with PBH, a chronic and debilitating condition with increasing prevalence as bariatric surgery remains a standard treatment for obesity.
3. Focused Pipeline Development in Orphan Neurodegenerative Diseases
Amylyx maintains active clinical programs in Wolfram syndrome and PSP with AMX0035, and in ALS with AMX0114. The company expects key data readouts in 2025, including Week 48 results from the Helios trial in Wolfram syndrome and an interim analysis from the Orion trial in PSP. These studies target diseases characterized by ER stress, mitochondrial dysfunction, and tau protein pathology, aligning with Amylyx’s strategic emphasis on mechanistically driven therapies for rare conditions.
4. Collaboration to Develop Long-Acting GLP-1 Antagonist
To extend its leadership in GLP-1 receptor antagonism, Amylyx entered a collaboration with Gubra A/S to develop a novel long-acting antagonist. This partnership aims to identify a lead candidate for IND-enabling studies, reflecting a forward-looking investment in pipeline expansion beyond PBH.
